invented? a new and useful CrudeJOil-Burning `Furnace, and they do hereby declare the `following to be iull, clear, and exact description of the invention, such as will enable others skilled inthe art to` which it appertains to malte and use the same.

The invention relates to crude oil burning turinices, particularly adapted 'for heating metal for welding or other purposes and has `tor tsobject tol provide a device of thia character wherein oilis projected into a combustion chamber which extends 'trom one Side of a heating chamber to a point above the heating chamber and is infconnnunication with the heating cliamberby a verti cally disposed passage or i'lue, in which the metal may be placed tor heating purposes. By projecting 'the blast into a combustion chamber, it will be seen that all particles oi the oil will be burnt and the products oi' combustion completely consumed, said products being consumed beiore they enter the heating chamber.

,a :further object is to provide a metal heating `furnace wherein the blast enters the heating chamber at an angle where the :Haines will not be projected through the furnace opening, thereby allowing an operator to come close to the furnace opening without being` burnt.

VVith the above and other objects in view the invention resides in the combination and arrangement oil i parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment ot' the invention may be made within the scope oit what is claimed i without departing from the spirit ot the invention.

casing, in which refractory material is placed for 'forming the furnace. The casing 1 comprises the bed plate which is secured by means ot bolts 'to supporting legs 4, which supporting legs support the furnace as a whole spaced irom the ground. Secured to the forward and rear edges ofthe bed plate 2 by means of bolts 5 are the front and rear sides 6 and 7 of the casing, said sides 6 and 7 being provided with reint'orc ing ribs 8 which preventing buckling` of the sides incident to intense heat. The ends ot the casing 1 arealso Jformed from metal, said ends being designated by the numerals 9 and 10. Tinds 9 and 10 are provided with -ianges 11, through which flanges and 'through elongated aperturesl)I in the ends o'l the front and rear sides 6 and '7 tie rods 13 extend, by means of which tie rods the metallic casing 1 is held together, the elongated apertures 12 allowing longitudinal eX- panson of the refractory material hereinafter described, which is disposed within the casing L The furnace passages and combustion chamber are 'formed either by a solid material, or any other way, however it preterably termed from refractory brick, theren by allowing lthe furnace to be quickly built and repaired.

ylhe 'turnace comprises a heating chamber 1li, which heating chamber is preferably located adjacent one end ot the furnace as a whole and extending upwardly from the heating chamber 14 is avertically disposed passage ot communication 15, through which passage a blast oi? lire passes downwardly into the heating chamber 14 from Athe end 16 oit the combustion chamber 17, thereby preventing the entrance ot the blast into the heating chamber at an angle where it will be projected through the furnace opening 18 which would prevent an operator closely ap preaching the furnace opening 18. The combustion chamber 1T extends towards the end 9 and is provided with a downwardly extending portion 19 which terminates substantialiy centrally ot the end 9 and in registration therewith is the burner aperture i2() in the plate 9. Disposed in the burner aperture 20 is a conventional form oi oil burner 21 which burner projects oil into the portion 19 of the combustion chamber where it is ignited. The tlame or blast passes through the elongated combustion chamber thereby causing the combustion of all the oil projected before it passes into the heating chamber 14 where it comes into cont-act with the article being heated. It will be seen that the blast is not a direct blast on the metal, therefore the metal will not become coated with oil which prevents the rapid heating of the metal. By consuming all of the oil in the combustion chamber it will be seen that the products of combustion such as gases will be consumed and will not leave the furnace.

T he topy of the combustion chamber 17 is formed with a transversely disposed arch 92 which arch is held together by bars 23 which engage the upper side of the arch and are provided with downwardly extending lugs 24 in which set screws 25 are threaded, said set screws forming means whereby the longitudinally disposed arch engagingbars 2G are forced into engagement with the sides of the arch for holding` said arch against falling, incident to extreme heat which will causeexpansion. It will be noted that the arch member may be easily removed for examining the interior of the furnace and for repairing the same.

/Vhen it is desired to light the furnace, this may be accomplished through the burner opening 20.

The invention have been set forth what is claimed as new and useful is A furnace comprising a heating chamber and an elongated combustion chamber, one end of said combustion chamber being` disposed above the heating` chamber and havin g a. passage of communication vertically disposed with the heating chamber, said combustion chamber extending downwardly to one side of the heating chamber, means for projecting fuel into the downwardly extending end of the combustion chamber, a metallic casing for the furnace comliirisingy hol'- tom. end and side plates, an aperture in one of the end plates in registration with the downwardly extending end of the combustion chamber for the reception of a, burner, transversely disposed clamping members for holding` the upper end of the furnace. and means whereby the metallic sides and ends may move in relation to each other incident to expansion.

ln testimony whereof we have signed our names to this specification in the presence of two subscribingl witnesses.
